Specification or Letters fatent, ,1 Pat t d 0 ,20, 1 14 Be it known thatI, CHARLEs M. Em tters,

citizen of the United States, residing at Elkhart, in the county ofElkhart andState of Indiana, have invented certain new and use fulImprovements 1n Lubricators, of which the followingv a specification.

My present invention relates to apparatus adapted to control fluid underpressure. so that this movement is in-accordance with the design ofcertain mechanisms or apparatus so as to maintain the same in good re-The principal object of my invention is to provide apparatus embodying acheck valve having seats spaced apart from each other and adjusted sothatthe movement of the fluid may be controlled to a nicety.

Other objects of my invention are to provide apparatus of the characterdescribed which is simple in construction and hence,

inexpensive to manufacture; an apparatus which may be embodied withexisting machines, such as gas engines or apparatus such as conduitsused in the transfer of fluid, under pressure, from one place toanother;and, apparatus which is positive in its action so as to avoid'accidentssuch as occur from excess pressure upon the fluid.

Other object of the invention will appear in the following detaildescription, taken in connection with the accompany ng drawings forminga part of the specification, and

in which drawings I Figure 1 is a view partly in section and partly inelevation disclosing apparatus constructed according to my invention;Fig. I

2 is a detail view in elevation showing means provldlng a valve seat.

In the drawings, where slmilar characters 7 refer to similar partsthroughout the views, A designates a chamber adapted to contain .fluidunder pressure; B a pipe in communication therewith; C a sleeve orconduit adjustable longitudinally with respect to pipe B; and, D asecond pipe in communication with the bore of sleeve 0. Within thesleeve G I provide a ball valve E and the pipe B is disposed in anupright position so that the ball valve normally rests upon the upperportion thereof due to the force of gravity.

Referring to the drawings,'wherein the invention is applied inconnectionwith apparatus for controlling the exhaust fluid from chamber A in orderthat a fluid, such App1ication filed May 13, 1913." Serial Nd. 767,353.1

'7 I as oill'inay be introduced into said chamber at suitable intervals,it is to be noted that the pipe B is formedwith the seat A pervioustO'flulCl regardless as to the position of ball valve E with o 're spectthereto. The lowerv portionof pipe'D provides seat 5, sothat when the,ball valve is raised and engages the said seat, fluid is prevented frompass ing from chamber A through pipe D. As a suitable means foradjusting seats 4 and 5 one with respect to the other, thefsleeve 3is"internally screw threaded as at 6 and v I 7, while the pipes B andDhave complimentary threads 8 and 9, respectively. Y The seat C is madepervious to fluid as by makingiincisions 10in theupper portion of thep1pe.'f A Tsshaped connection/11 may a provide an exhaust way12,"bringing the a pipe D in communication with the atmos- I phere asthrough the exhaust dome 13. surmounted upon fitting 11 I have providedan oil cup 14 of any suitable type, and having means 15 in the form of ascrew threaded ste n, which provides a way-16 incoinmunication with thebore'of'pipe D. The way 16 is relatively smaller than the exhaust-way 12so that any fluid which passes valveE from chamber A may pass mosphere.I

I find desirable to providea nut lock 17 so that when'the seats 4 and 5are spaced apart from each othera desired distance the freely to the at?adjustment will not be altered I by -vibr'ation of the several elements.g

The operation of. he apparatus disclosed in Figs. 1 and 2 is as follows:Assuming that the chamber 9 is a cylinder of a gas engine, andthat itis desired to introduceoil thereinto, this oil, which drops by gravitythrough ways 16 into pipe D, is permitted to pass valveoE and into pipeB as through the incisions 10. As the piston in cylinder 9 moves forexhaust or compression of fluid in the cylinder, the valve E is quicklyraised.

and engages seat 5. Suchfluid as finds its way past valve E from chamber9 is quickly exhausted to the atmosphere and has little effect upon theoil flowing by gravity from the cup 14. As soon as the pressure ismaterially reduced in the cylinder 9, or the piston moves in its intakestroke, the valve E drops by gravity and oil passes by seat C on intochamber A.

Iclaim: j 3 y, 1. In a lubricator adapted to be connected y to a fluidpressure chamber, the combination of a chamber adapted to contain fluidunder pressure, an upright pipe in communication therewith and havingits upper end formed to provide a pervious valve seat, a sleeveadjustable longitudinally of said pipe, a valve in said sleeve, a secondpipeadjustable longitudinally of said sleeve and providing a seat forsaid valve, said seat being disposed above the latter to prevent passageof fluid through said second mentioned pipe from said chamber when saidvalve is seated thereon, a means providing an exhaust to the atmospherefrom said second mentioned pipe and above the seat thereof, and meansproviding a way for introduction of fluid to said second mentioned pipeabove the seat thereof. j Q e 2. In a lubricator adapted to'be connectedto afluid pressure chamber, the combinationof a chamber adapted tocontain fluid under pressure, an upright pipe in communication:therewith and having its upper end formed to provide a pervious valveseat, a sleeve adjustable longitudinally of said pipe, a valve in saidsleeve, a second pipe adjustable longitudinally of said sleeve andproviding a seat for said valve, said seat being disposed above thelatter to prevent passage of fluid through said second mentloned plpefrom said chamber When said valve is seated thereon, a means providingan exhaust to the atmosphere from said second mentioned pipe and abovethe seat thereof, and means providing a way for introduction of fluid tosaid second mentioned pipe above the seat thereof, said way beingrelatively smaller than the said exhaust, substantially as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
